HENRY REESE, OF BALTIMORE, MARYLAND.

TREADLE.

SPECIFICATION forming part of Letters Patent No. 262,246, dated August8, 1882.

Application filed May 18, 1852.

To all whom it may concern:

Be it known that I, HENRY REESE, of the city of Baltimore, and State ofMaryland, have invented certain Improvements in Treadles, of which thefollowing is, a specification.

My invention relates to the construction of treadles-snch as are usedfor driving sewingniachines and other similar purposes-its object beingto produce an articulated treadle, which shall work with the leastpossible friction and be cheaply made.

Figure l of the accompanyingdrawings is a plan ot' my improved treadle.Fig. 2 is an inverted plan thereof. Fig. 3 is a vertical section cut inthe plane of thelines 3 3 in Figs. l and 2. Fig. et is a section out inthe plane of the lines 4 et in said figures. Fig. 5 is a verticallongitudinal section of the foot-rest on a larger scale, cut in theplane of the lines 5 5, and Fig. 6 is a transverse section thereof, cutin the plane of the lines 6 G.

' Let A designate the usual cross-bar near the t1oor,on which thetreadle of a sewing-machine is commonly fulcrumed. Beneath this bar I xtwo knife-edge supports, B B, (shown best in Figs. 2 and 4,) which aresuspended from the' bar by means of eyes or perforated lugs a a, formedbest in one piece with the knife-edges, which lugs are passed over thebar and fixed to it by set-screws or otherwise. I have shown the twoknife-edge supports B B as joined together by a bar, b; but this is notessential, although I consider it the preferable construction.

C is the main frame of my treadle, which is fulcrumed on the knife-edgesB B, having angular notches o o, into which the knife-edges project. Theframe C rocks on these knifeedges without appreciable friction. Itsvertical displacement is prevented by slots d d immediately above thenotches o c, through which slots the rod A passes without touching them,except when the frame Gis lifted. The lateral displacement ofthe frameis prevented by the lugs a a, between which it is contined.

The frame G extends to front and rear of its fulcrum, and bears twofoot-rests or insteptreadles, D D, one for the right and the other forthc left foot of the operator. These fcotrests are so mounted as to havea rocking motion, 1n similar manner to those shown in my (No model.)

patents of February 1, 1876, No. 173,059, and July 18, 1876, No.180,066, and for the purpose therein explained of imparting an easymotion to the feet and legs. On the frame G, at each foot-rest, areformed two vertical lugs or Walls, o e, between which extends a bar, f,on the upper edge of which, adjacent to the walls e e, are formedknifeedges g g. Each foot-rest D is formed preferably with a curved androughened upper surface, and with two ears projecting downward therefromon opposite sides, and tting between the walls e e. These ears haveangular notches L h formed in them, and these notches engage thelinifeedges g g, on which the foot-rest can freely rock.

An eye, j, of wire, extends under the bar f, beneath each knife-edge g,(or one eye in the middle might serve the purpose,) and its ends arefixed to the foot-rest, preferably' by passing up through holes therein,and their protruding portions clinched or riveted down thereon. Theseeyes serve to prevent the foot-rest being lifted offthe knife-edges orotherwise displaced. From one or each side of each foot-rest an ear,

7c, projects and enters between two stops, l 1

on the top ot the wall e. These stops intercept the movement of the earsas the foot-rest is rocked, and so limit the play of the latter, therebypreventing its being rocked to too great an extent.

At the back ofthe frame C is formed a projecting knuckle, m, to which tojoint the pitman through which the treadle drives thecrank.

My improved treadle has an easy, noiseless, and almost absolutelyfrictionless motion. Its use avoids the fatigue ot" the ankles so oftenfelt in running a sewing-machine with the ordinary treadle, and it canbe manufactured at an extremely low price.

I claim as my invention- 1. rIhe combination ot' knife-edge supports BB, provided with lugs a c, and treadle-frame (J, having angular notchesc c engaging said knife-edges, substantially'as set forth.

2. The combination of knife-edge supports B B, provided with perforatedlugs a a, and

treadle-frame U, having notches o c, and formed with slots d cl,arranged opposite and to coincide with the perforations in the lugs a a,to engage the transverse treadlerod of a sewing or other machine,substantially as described.

IOO

rest D, having notches h h, and wire eye or eyesj, substantially as setforth.

7. The combination of treadle-frame C, having walls c e, knife-edges gg, and stops l l, of foot-rest D, having notches h h, and ear or ears7c, substantially as set forth.

In witness whereotl I have hereunto signed my naine in the presence oftwo subscribing witnesses.
